A furrow opener 5 implement is towed by the vehicle and an engine rotates the vehicle wheels and two or more implement wheels. A pneumatic distribution system conveys dispensed products to the furrow openers. The external guidance system sends location signals indicating a location of the implement frame to the operator. Steering, metering, and distribution signals are sent by both the external guidance system and an operator with a remote 10 operator control, and operator signals override signals from the external guidance system.37 25 31 393 52 5 FIGURE 1 35R 51 5B 23 15A 03 150 P 2132 25 9 25 PA 11 1 3 311B 9 FIGURE 2
